It should be noted that the description of these embodiments is intended to aid understanding of the present invention and does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are merely intended to describe exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms, and should not be construed as being limited to the embodiments described herein.

[0023] like Figure 1 、 Figure 2 As shown, Figure 1 A schematic structural diagram of a drain device from a first angle is provided for an embodiment of the present application. Figure 2 A second angle structural schematic diagram of a liquid discharge device is provided for an embodiment of the present application; a liquid discharge device, the liquid discharge device comprising a main body 101 for accommodating a working medium, a first working cavity being provided in the main body 101, an operating cover 102 being movably provided on the main body 101, the operating cover 102 being switchable between an open or closed working state on the main body 101, and when the operating cover 102 is in the closed working state, the operating cover 102 and the main body 101 form a relatively sealed first working cavity, so that after the working medium is added to the first working cavity, the stable storage of the working medium is ensured.

[0024] like Figure 1 As shown, the main body 101 is penetrated by a first connecting pipe 201 and a second connecting pipe 202 respectively connected to the first working cavity, the first connecting pipe 201 is provided with a first control valve 301 for controlling the conduction state in the first connecting pipe 201, and the second connecting pipe 202 is provided with a second control valve 302 for controlling the conduction state in the second connecting pipe 202.

[0025] In actual configuration, the first control valve 301 and the second control valve 302 are used to control the flow of fluid in the first connecting pipe 201 and the second connecting pipe 202 respectively. Gate valves, stop valves, butterfly valves or ball valves can be actually used, and the first control valve 301 and the second control valve 302 can be controlled manually or arranged as a control system for centralized control.

[0026] In an optional embodiment, the working principle of the liquid discharge device in the present application is as follows: the liquid discharge device includes a main body 101 for accommodating an operating medium, a first operating cavity is provided in the main body 101, an operating cover 102 is movably provided on the main body 101, and the operating cover 102 can be switched to an open or closed operating state on the main body 101, and a first connecting pipe 201 and a second connecting pipe 202 are respectively connected to the first operating cavity on the main body 101, the first connecting pipe 201 is provided with a first control valve 301 for controlling the conduction state in the first connecting pipe 201, and the second connecting pipe 202 is provided with a second control valve 302 for controlling the conduction state in the second connecting pipe 202, During actual operation, the operating medium can be introduced into the first operating cavity of the main body 101 through the first connecting pipe 201 according to the operating needs, and the second connecting pipe 202 can be controlled to discharge the liquid through the operation of the second control valve 302. The relatively closed first operating cavity maintains the reliability and safety of the liquid discharge process, improves the environmental protection indicators and the operational controllability of the operating environment, and the operating cover 102 that can be opened or closed can facilitate the opening and observation operation under special working conditions while maintaining the relative sealing of the first operating cavity. When performing operations such as pump body maintenance and blockage treatment, the first control valve 301 and the second control valve 302 are combined to meet the specific operating conditions, improve the safety and controllability of the operation, and can be flexibly adapted to coking operation production.

[0027] like Figure 1 、 Figure 2 As shown, in an optional embodiment, a locking device is further provided on the main body 101, and the locking device is arranged on one side of the operating cover 102. The other side of the operating cover 102 is rotatably connected to the main body 101, and the locking device can limit the operating cover 102 from switching to an open operating state.

[0028] The setting of the locking device can effectively and stably and reliably constrain the operating cover 102 in different operating conditions to keep the operating cover 102 in a closed state, avoid leakage or misoperation at the operating cover 102, and improve the reliability of the main body 101 and the operating cover 102.

[0029] like Figure 1 、 Figure 2 As shown, in an optional embodiment, the locking device includes a movably connected base 401 and a pressing portion 402, the base 401 is fixed on the main body 101, and the pressing portion 402 can move back and forth at one end away from the base 401. When the operating cover 102 is switched to a closed operating state, the pressing portion 402 can be displaced and pressed on the operating cover 102 to limit the operating cover 102 from switching to an open operating state.

[0030] The base 401 is fixedly connected to the main body 101, providing an operating installation foundation for the pressing part 402. When the operating cover 102 is constrained, the pressing part 402 moves on the base 401, and the pressing part 402 moves close to the base 401 until the pressing part 402 is pressed on the operating cover 102, applying force to the operating cover 102 to keep the operating cover 102 pressed on the main body 101.

[0031] like Figure 1 As shown, in an optional embodiment, the pressing portion 402 includes a pressing rod 403 and a connecting rod 404, the connecting rod 404 can be telescopically arranged, the connecting rod 404 can be rotatably connected to the base 401, and an opening groove 103 is provided on the operating cover 102, the opening groove 103 can accommodate the connecting rod 404, and the pressing rod 403 is pressed on the operating cover 102.

[0032] The specific displacement of the pressure rod 403 is achieved by the telescopic operation of the connecting rod 404. When the operating cover 102 is closed, the connecting rod 404 can be driven to retract, and the pressing part 402 can be driven to approach the operating cover 102 until it is pressed onto the operating cover 102. It should be noted that since the operating cover 102 is opened and closed by rotation, during the rotation of the operating cover 102, the open groove 103 provides an avoidance position for the connecting rod 404 and the operating cover 102 to avoid interference between the connecting rod 404 and the operating cover 102. Furthermore, the connecting rod 404 is also rotatably connected to the base 401, and synchronously maintains the smoothness of opening and closing of the operating cover 102 through the relative rotation of the connecting rod 404. In addition, when operating the operating cover 102, the connecting rod 404 can also be rotated to a suitable position to provide more space for the operator to operate above the first working cavity.

[0033] like Figure 1 As shown, in an optional embodiment, the connecting rod 404 includes a screw rod 405 and a sleeve 406 that are threadedly connected. The screw rod 405 is connected to the base 401 , and the sleeve 406 is fixedly connected to the pressure rod 403 .

[0034] The relative rotation of the screw rod 405 and the sleeve 406 completes the telescopic operation of the connecting rod 404, so that the pressure rod 403 moves up and down.

[0035] In actual arrangement, the connecting rod 404 may also be configured as an electric telescopic rod.

[0036] like Figure 1 、 Figure 2As shown, in an optional embodiment, the sleeve 406 and the pressure rod 403 are welded and fixed in a T-shape. During actual operation, the pressure rod 403 can be welded and fixed to the connecting rod 404 in a mutually perpendicular state to maintain a more uniform contact state between the pressure rod 403 and the operating cover 102, thereby improving operation stability.

[0037] like Figure 1 、 Figure 2 As shown, in an optional embodiment, a third connecting pipe 203 communicating with the first working cavity is further provided through the main body 101 , and a third control valve 303 is provided on the third connecting pipe 203 .

[0038] When the third connecting pipe 203 is used for sampling operation, the working medium is discharged through the third connecting pipe 203, which is convenient for flexible sampling according to the working needs, and the relative sealing of the first working space is ensured by the control operation of the third control valve 303. The third control valve 303 is used to control the flow of the fluid in the third connecting pipe 203. A gate valve, a stop valve, a butterfly valve or a ball valve can be actually used, and the third control valve 303 can be controlled manually or arranged as a control system for centralized control.

[0039] like Figure 1 、 Figure 2 As shown, in an optional embodiment, in the vertical reference direction from the top to the bottom of the first working cavity, the height of the first connecting pipe 201, the height of the third connecting pipe 203 and the height of the second connecting pipe 202 are arranged in sequence.

[0040] The first connecting tube 201 can be used as a component related to adding the working medium, and the second connecting tube 202 can be used as a component related to discharging the working medium. The working medium enters the first working cavity through the first connecting tube 201 and can be discharged from the first working cavity through the second connecting tube 202. This process does not require the displacement operation of the main body 101. The working medium is discharged smoothly and sampling operations can be flexibly performed through the third connecting tube 203.

[0041] In an optional embodiment, a bracket 104 is provided under the main body 101 to keep the main body 101 arranged at a suitable position and height in the working area.

[0042] In an optional embodiment, a sealing member is provided between the operating cover 102 and the main body 101 , and the sealing member may be a rubber ring to improve the sealing performance of the first working cavity.
